Question

Скорость распространения волны равна 15 м/с . определите частоту колебаний источника если длина волны равна 50 см

Answer 1

Дано: V=15 М/С
λ =50 см=0,5 м
Найти: ν
Решение. ν=V / λ,  ν =15 М/С : 0,5 М =30 Гц
Ответ: частота ν =30 Гц

Answer 2

Calculation of Frequency

To determine the frequency of the source's oscillations, we can use the formula:

Speed of wave = Frequency × Wavelength

Given that the speed of the wave is 15 m/s and the wavelength is 50 cm (or 0.5 m), we can substitute these values into the formula to solve for the frequency.

15 m/s = Frequency × 0.5 m

To find the frequency, we can rearrange the equation:

Frequency = Speed of wave / Wavelength

Substituting the values:

Frequency = 15 m/s / 0.5 m = 30 Hz

Therefore, the frequency of the source's oscillations is 30 Hz.
